Q1.
Look at the pictures. Now, discuss the following points. • Sources of water • Without water there cannot be any life • Value of water and the need to save it
Answer

The pictures on page 74 show a river running through green trees, a pond, a stream drying up into a few muddy puddles, and a hand turning off a tap that is running into a basin. Discuss them point by point.

PointWhat to say
Sources of waterRain; rivers, streams and canals; ponds, lakes and tanks; wells, hand pumps and tube wells (groundwater); springs; melting snow from the Himalayas; the sea (salty, and therefore not fit for drinking without treatment).
Without water there cannot be any lifeAbout two-thirds of the human body is water. We need it to drink, cook, bathe and clean. Crops die without irrigation; cattle, birds, fish and trees all perish. The drying stream in the picture shows what happens to every living thing around it.
Value of water and the need to save itOnly a very small part of the earth's water is fresh and usable, and it is not replaced quickly. In many villages and towns women and children walk long distances for a few pots. A tap left running, as in the picture, wastes in minutes what someone else must walk an hour to fetch.

Simple ways to save water at home and at school: close the tap while brushing your teeth or soaping your hands; take a bucket bath instead of a shower; mend leaking taps at once; reuse the water in which vegetables or rice were washed to water plants; harvest rainwater from the roof; water the garden early in the morning so that less evaporates.

Q2.
Make a poster with a meaningful slogan on ‘Save Water.’
Answer

How to make a poster that works:

  1. One idea only. A poster is read from a distance in three seconds, so do not crowd it with sentences.
  2. A big slogan in the upper half, in thick capital letters.
  3. One strong picture — a dripping tap counted in falling drops, half the earth as a water drop, or a child and a plant sharing one glass.
  4. Two or three colours only — blue for water, green for life, black for the letters.
  5. One small line at the bottom telling people what to do: “Close the tap while brushing.”
Sample slogans:
  • Save water today, or search for it tomorrow.
  • Every drop counts — don't let it run!
  • Water is life. Do not let life go down the drain.
  • जल है तो कल है — If there is water, there is a tomorrow.
  • A closed tap is an open heart — save water for someone else.
Why a slogan is short: Notice that every slogan above is under eight words and most of them use rhyme, repetition or a play on words. That is what makes a line stick in the reader's memory long after he has walked past the poster.
